Product Description
Rotary Rock Drilling Tricone Drill Bit with Open Bearing Steel Tooth Forging Type
Introduction
Cutting Structure
The durability of premium tungsten carbide insert is improved with new formulas and new techniques and new techniques. The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces.
Bearing Structure
Non-sealed roller bearing. Drilling fluid can enter the bearing directly for cooling; Balls lock the cone which reduces the probability of cone dropping to minimum.
Product Application
It is suitable for the shallow well, water well and geothermal well.
